Thanks for the history Lloyd; I did not know all of that. After I bought my 520 pump-gun, I found another front end for it in 26" IC choke. The 26 incher has a patterned barrel top, but unfortunately does not fit very well and is difficult to pump. I'll get around to having a gun-smith free it up at some point.




The take-down procedure on these guns is unique in my experience...Geo
P.S.: Sorry for getting off topic
